TO WHOM IT MAY CONCERN:

Be it linown that I, I. N. Sunrmpf Brooklyn, county of Kings, and State of New York, have invented a new and improved mode of Desnlph'urizing Gold, Silver, and other Ores, and pyritous substances constructed of fire-clay, plumbago, nauielled iron, or any refractory material, as herein set forth; and I hereby declare that the-followin'g-is a full add exact-description th'ereofl i'efcrcnce being held to -the accompanying drawings,

The nature of my invention consists of a furnace or oven of circular form of any suitable size. The floor a upon which the ore is roasted is constr'ucted of fire-clay, tile, or brick, or any other refractory material. The

conveyors A are also constructed of fire-clay, or any other refractory substance. The upright shaft K, which is exposed to the action of gaaes and heat, is also covered and protected by tlie same a'naterisl of which the conveyors aromatic, as shown on sheet No. 2, figsNos) 5 and 7; and arms F F, upon which eonveyers A A are placed, are entirely protected from the action of the heat and gases by the conveyors themselves. The furnace or oven is so constructed that the heat is conveyed uniformly under the floor or hearth, and exte'ndingover the topof' the furnace by lines conducting it to the chimney under a drying-floor, (should it be needed.)

The method of operating myfurnace is as follows: The ore pulverized is placed into a hopper near the centre of the furnacqand is conveyed-through a tube-of fire-clay or other material of a refractorysnatui'e,

' near'the centre of the oven B, and'is from thence conveyed in a circular manner from the centre to the circus 1 fercnoe, where it passes through an opening,J,- into a receiver for amalgamation or other treatment.

To enable others to make. and use my invention, I describe its construction and operation. In the construction of this oven, I provide openings through the walls or arch, at convenient points, for the purpose of inspection and other uses, as employed in ordinary furnaces; and in applying the power foithe operation of shaft and conveyor arms, I do not confine myself to the arrangement of shaft below, as shown .iig. 1, as it may be more convenient in some cases to apply the power from above; nor'do I confine myself to the use of gears G'G, as it may be desirable to substitute a worm and gear instead. In arranging-the conveyors A A, as hereinafter described, the object is twofold: first, to move the ores or other material, when being treated,

by a conveycr that eannot'be afi'ected bythc action ofthe heat andgases to which they are exposed; and secdad, to protect the arms F F from'the action of the same destructive elements so detrimental to desnlphurizers heretofore constructed, -In the arrangement of the condcnserN and its connecting pipes O, P, and Q, the object is' also twofold: first, oven B is exhausted by a jet of 'steam or air as applied forcing the gases throughwater, thereby preventing any loss of the precious metals; second, the utilization of the gases and steam after passing through the water to the furnace, as described hereafter. The advantages of thel(ollow shaftK and arms -F'F,

,as'a means of conveying oxygen to the desired point in the treatment of ores, &c., will be nndcrstoodand appreciated by all who know what is required in the proper treatment of minerals, and also for the introduction of chlorine gas, useful in the treatment of silver ores, and as afi'ording additional protection to said shaftand arms from heat to that which they receive from thekconveyers A A, itc- But I do not confine myselfwhdlly to this mode of supplying oxygen-to the ores when being treated, as it may be important to admit it at otherpcints.

Figure 5 shows a section of shaft K and arms F F, which are made of iron or other metal, with the con-'- voyors A A, openings W W, box or jacket M, and connecting or inlet pipe V for the admission of oxygen.

Figure 6 is a plan of conveyors A A, the blades of which are seen by dotted lines. Figure 7 is a sectional or end view of' arm F with conveyor A. What I claim as my invention,- and desire in Letters Patent, is- 1. Au oven B, revolving' arms F F, and upright shaft K, operated by means oi gears G G and horizontal shaft H, or their equivalents, substantially as described.

f2. I claim the co'rii' eying the ores or-other material, while being operated upon, from the central part of oven B to the circumference, and there discharging them, or from the circumference to the centre, as may be desired, by means of conveyors A A connected to arms]? F, as shown on fig. 5, substantially as described. I

3. I claim the use of fir-clay, p1umbago, or graphite, enamelled iron or other metals, oranyothcr refractory material, for the construction of conveyors A A, and for the protection of the upright shaft K and arms F F that-are exposed to the action of heat and gases, substantially as described., 4., I claim the construction of fines C G underneath the oven B so as to give a uniform heat, also, flucs D .1) leading from underneath the floor' and over th'e'arch of even B in its passage to the drying-floor or chimney, substantially as described. i '5. I claim a stationary 061 of the oven B, substantially as described.

6. I claim the supplying the'necessary oxygen for the proper treatment of ores, or-other material for which the even. my; be ndnpted, through the supply" pipe V, box. M, ,shaft K, and aru'i F F and openings WW, through said arms F F and conveyers A A, thereby preventing the arms F F from becoming-too much heated when in tandem-substantially as described. i

. 7. I claim the outlet W, for conducting gases-or other volatile substances, and pipe with its connections, to condenser N,'anc l the steam or air jet 'Q, for the purpose of exhausting the gases, &c., from oven B; also chambers, when usedinconnection'xvithtldsfnrnace,.whioh may be required for the treatment of such ores as cinnnbsr, zinc, lead, &c., or the manufactur of sulphuric or other acids, and for conducting the same through water, thence to the furnaces T 1 through pipes PP, where both the gasesand steam or air are to be used ,to assist combustionl when-not otherwise disposed of, thereby eeonomiaing fuel, substantially as and for the purposes described. 4 i 1 8. I clai'm the hollow shaft K and arms A A for the purposes named in the foregoing specifications or their equivalent, substantially and for; the purposes described.
